Bookmarks include, in addition to links, cookies, passwords, favorites.
The following image with link show the correct method to recover your bookmarks if corrupt. I successfully tested the method on another machine by deliberately deleting all my links, passwords, cookies.
I would suggest you to use password manager like Keepass or Bitwarden. Way more secure and private.
Just my 2 cents.
Hope you manage to get your passwords back.
Have you had any luck with this? Same thing happened to me and it’s been 4 days now. And this involves 391 passwords! Let me know if you have a breakthrough/solution.
